KVM and VMware ESXi are leading contenders in the virtualization market. VMware ESXi often gains preference for its extensive features and superior performance.
Features: KVM offers flexible open-source usage, strong networking, and seamless Linux integration. VMware ESXi provides features like high availability, VMotion for live migrations, and robust management tools.
Room for Improvement: KVM could enhance its setup simplicity and comprehensive documentation to reduce deployment complexity. Additionally, it would benefit from improved user interface options. VMware ESXi could improve its cost model to be more competitive and increase scalability options, while further simplifying its user interface for complex tasks.
Ease of Deployment and Customer Service: KVM requires detailed manual configurations but has a strong community support system. VMware ESXi provides a straightforward setup with robust enterprise-grade support and guidance.
Pricing and ROI: KVM's open-source nature minimizes costs, increasing ROI for budget-sensitive setups. VMware ESXi demands higher licensing fees but offers features that may justify long-term investment for resourceful enterprises.
KVM definitely saves costs since it is open-source and does not obligate us to pay for licenses as necessary with other virtualization solutions.
The management burden decreased from a 20-person team to just five or six people providing 24/7 support.
Paid support is also obtainable from companies like Red Hat for more critical issues.
I rate the technical support from VMware as nine or ten out of ten.
In the last three or four years, we did not require any support from VMware engineers, indicating its high reliability.
Customer service and support are good; they are reachable, and at times remote support suffices.
The solution is scalable, allowing us to scale up or down regardless of infrastructure size.
vCenter Server can manage up to 1,000 ESXi servers within a single UI interface, allowing extensive deployment and management capabilities.
My customers are highly satisfied with its scalability.
ESXi is stable, and our business operations depend on it year after year.
Stability rates a perfect 10.
In comparison to VMware, which offers a more balanced set of management features, KVM could improve in terms of user-friendly tooling.
Providing a mobile application for remote access to ESXi servers would be beneficial.
It's not cost-effective for small users and creates a gap for alternatives, while favoring larger clients.
The cost of VMware ESXi is very high, especially after the acquisition by Broadcom, which led to price increases.
Compared to VMware and Microsoft, KVM offers better pricing and licensing options.
The product is very cost-effective, though not fixed, as pricing tends to fluctuate over time.
The solution is moderately priced, not exactly cheap yet not overly expensive either.
The pricing is expensive, with the cost for customers ranging from $10,000 to $20,000 yearly.
The most valuable feature of KVM is its superior real-time performance, which results in lower latency compared to alternatives like VMware and Microsoft.
Its capability to move virtual machines to physical machines is very efficient for our live environment.
As a level one or bare metal hypervisor, its unmatched scalability depends on underlying hardware, capable of managing large numbers of physical servers with one management platform.
vMotion is a daily used technology that allows us to have machines distributed across different sites while maintaining redundancy between the sites.
